Low water pressure can be frustrating. Whether you notice it while taking a shower, washing dishes, or using your outdoor hose, a sudden drop in water pressure is usually a sign that something in your plumbing system has changed. While some causes are minor, others can indicate larger plumbing issues that need attention.
For homeowners in Mission, BC, understanding the common causes of low water pressure can help you identify when it’s a simple fix and when it’s time to call a professional plumber.
Common Causes of Sudden Water Pressure Loss
Mineral Buildup in Pipes
Over time, mineral deposits from hard water can build up inside plumbing pipes and fixtures. This buildup gradually reduces the diameter of the pipe, restricting water flow and lowering pressure. Faucets and showerheads are often the first places where this becomes noticeable.
Cleaning or replacing clogged fixtures can sometimes restore normal pressure.
Partially Closed Shut-Off Valves
If the main water valve or the shut-off valve near your water meter is partially closed, it can significantly reduce water pressure throughout the home. This can sometimes happen after plumbing repairs or maintenance.
Checking that these valves are fully open is a quick step that can occasionally resolve the issue.
Hidden Plumbing Leaks
A leak somewhere in your plumbing system can divert water away from fixtures, resulting in reduced pressure. Signs of a possible leak include unusually high water bills, damp spots, or the sound of running water when nothing is turned on.
Leaks should be addressed quickly, as they can lead to property damage and higher repair costs if left unresolved.
Pressure Regulator Problems
Many homes use a pressure regulator to control the amount of water entering the plumbing system. If this device fails or begins to wear out, it can cause noticeable changes in water pressure.
A malfunctioning pressure regulator typically needs to be replaced by a professional plumber.
Municipal Water Supply Issues
Sometimes the issue may not be inside your home at all. Maintenance work, water main repairs, or temporary supply changes can affect water pressure in certain neighbourhoods of Mission, BC.
If the pressure drop happened suddenly, it can be worth checking with neighbours to see if they are experiencing the same issue.
When Low Water Pressure Affects Only One Fixture
If only one faucet or shower has low pressure, the problem is usually localized. The most common causes include:
- A clogged aerator on the faucet
- Mineral buildup inside the showerhead
- Debris caught in a supply line
Cleaning or replacing the fixture often solves this type of issue.
When the Entire House Has Low Water Pressure
When every faucet and fixture in the home is affected, the cause is usually related to the main water supply or the home’s plumbing system. This could include:
- A partially closed main shut-off valve
- A failing pressure regulator
- A leak in the main water line
- Municipal supply issues
Identifying the source early can help prevent further plumbing complications.
